Do you have any links to any websites other than Ebay for these ? I seen small honda powered ones that look like they can be carried by hand, I take it they are no use (not powerful enough) ?

What event duration do you need to cover... just a few hours or all night? You could run that on a 4500-5000w gas genset but if you need more than 5-6 hrs run time a diesel would be the better choice.

5-6 hours run time should be fine to be honest. (can you re fill with diesel while running worse case scenario that you think you may be running low)

No generator should be refueled while running... same as any piece of machinery.

I've been running petrol gen sets for outdoor parties refueling them drunk while running, for over 10 years. Sometimes it's kinda scary but never any problem even spilling a lot of fuel on it. Take it for what it's worth I would not recommend it but I'm alive and well.
I've used both inverters and cheap Chinese non inverted ones with pioneer cdjs, non inverted ones work well with iron amps and my smps JBL eon tops but not sure how they would work with big smps amps. Kipor inverter gen sets has worked fine for me

Yeah you are quite lucky then mate....the exhaust on a small engine that's been running for hours, is usually hotter than the flash point of petrol!
It's a little safer with diesel, as the flash point is that much higher. Still not a great idea. In general diesel gensets are better, as the flywheel is heavier and so the RPM is more stable. Petrol sets run faster, with a smaller flywheel, and can more easily overspeed (producing abnormally high voltage and frequency) if a large electrical load suddenly drops off. EG absolute worst case scenario is a cascade failure: you blow your bass bins - the bass amp load drops off - the genny overspeeds - voltage goes to 300V+ for a second - this blows up your DJ gear - party over. That's why it's considered best practice to have at least 1kVa, preferably more, "spare" capacity in the genset compared to what you need. You can then use a 500 watt floodlight as a constant load, to help keep the speed level.

All of the better commercial gensets (gas or diesel) have automatic voltage regulation so that is something to look for. I have run the larger parade system mentioned above which includes smps amplifiers on commercial non inverter generators for the last few years with no issues.

Based on what you have said above
I think I need to try and source myself some a 6.5 KVA with a built in regulator (diesel) and I should be fine with no troubles then Just need to source some for reasonable value, Appreciate all your help

theres lots out there, and i linked you to the kind of sized unit i would recommend. Whilst shite like Kipor are everywhere and cheap, i can't recommend them. Up to you if you listen to that or chance it. Likewise, if you find something 'lightweight & portable', whilst it may work, for a time, its your risk. depends whether you're providing a professional service, a budget disco, or a free party suicide rig.

Flash point isn't when it goes bang, you're thinking autoignition temperature. Both pretty important in terms of risk assessment but autoignition temp is the most important IMO.
